Title: Liquidus epitaxial growth
Inventor: HAYASHI HIROSHI
IPC: H01L21/208
Filed: 1979-09-26
Abstract: PURPOSE:To check the occurrence of an oxide film or slag by controlling the saturation of solute immediately before contacting a substrate with the lowest temperature part of a fusing solution providing temperature difference. CONSTITUTION:The lowest temperature part 4 of a Ga fusing solution contacts a GaAs source substrate 5 until just before the beginning of epitaxial growth. Therefore, the Ga fusing solution is always clean and the growth to the GaAs substrate 5 maintained at the same temperature with a GaAs substrate 1 is adjusted by melt back even if the diffusion flow of As in the Ga fusing solution 3 causes excess and deficiency by a difference in holding time. Therefore, the As concentration at the lowest temperature part 4 of the Ga fusing solution at the time immediately before the beginning of growth exactly becomes the saturation concentration at a substrate temperature. Furthermore, with source GaAs installed at the upper and lower parts of the Ga fusing solution, the time requiring to saturate the concentration to a predetermined concentration will remarkably be reduced. The same effect with single layer growth will be obtained by contacting the source substrate with the lowest temperature part of each fusing solution for temperature difference multilayer growth using two or more fusing solutions.

Title: Focusing device
Inventor: SUZUKI NOBUO
IPC: G02B7/34
Filed: 1980-09-10
Abstract: PURPOSE:To decide an in-focus state with high precision by performing operation, which corresponds to the forward and backward movements of a lens system by electric processing and by determining the position of the in-focus state. CONSTITUTION:Electric signals A' and B' are generated by the photosensitive parts 9 and 10 of an image sensor 6 respectively. The signals A' and B' for the (i)-th picture element are compared mutually and the resulting output is denoted as C0; and the signal A' for the (i)-th picture element and the signal B' for the (i-k)-th picture element are compared to obtain the output C-, and the signal A' for the (i)-th picture element and the signal B' for the (i+k)-th picture element are compared to obtain the output C+. In this case, the C0 is smallest in an in-focus state as shown by figure 62. When a lens 1 comes close to a main imaging surface 3 from a focusing state as shown by figure 61, the C0 increases and the C- is the smllest. In the opposite case, the C+ signal is smallest as shown by figure 63. Therefore, an in-focus state is decided precisely on the basis of the relation among the C0, C+ and C-.

Filed: 1979-09-27
Abstract: PURPOSE: To reduce a transfer time, by providing a buffer between the peripheral control equipment and the peripheral equipment, and transferring a data independently between the buffer and each equipment.  
     CONSTITUTION: In case it is desired to transfer 18 bytes to the peripheral equipment 32 from the central processing unit 33, the processing unit 33 writes 16 bytes in the first-in first-out (FIFO) memory 2 under control of the control equipment 32. The value of 11 is set to the counter 11, and the flip-flop (FF)121 is set. When transfer of a data of 1 byte has been finished, a pulse is sent out to a signal line 102, the value of the counter 11 is subtracted by 1, and in case of underflow, an output is generated in a signal line 101. As a result, FF121 is reset, FF14 is set, and the remaining 2 bytes are written in the memory 2. After that, FFs 13, 121 are set, and the same operation is executed. Transfer of the final byte is informed by FF13.

Filed: 1983-07-11
Abstract: PURPOSE:To facilitate control of development density in accordance with change of developing conditions by enabling control of the speed of the developer to be fed to a developing region in accordance with developing conditions. CONSTITUTION:When original density changes or the potential of an electrostatic latent image changes due to other causes, developing conditions are also changed, and when its change amounts up to 20-30%, the rotation speed of a developing sleeve 2 is changed to change the speed of feed of a developer to a developing region, and thus, recorded image density can be maintained constant. The feed speed of the developer to the developing region can also be controlled by changing the rotation speed of a magnet 3 in the arrow direction. The relationship between the rotation speed (r.p.m.) of the magnet 3 in the X-axis and recorded image density in the Y-axis as shown in the graph is obtained by fixing the rotation speed of the sleeve 2 in the arrow direction to 65r.p.m. and changing the rotation speed of the magnet 3.

Abstract: PURPOSE:To make it possible to dehumidify inside a room without using energy such as electricity, preventing harmful outdoor object from getting into a room, by attaching a water-vapor semipermeable membrane at an opening so as to be opened and closed. CONSTITUTION:A transparent water-vapor semipermeable membrane 1 such as polydimethylsiloxane membrane etc. is formed into an accordion-type panel, one end of which is attached to the outside end of a window 2 and the other end is attached to a window frame 3. When the window 2 is opened, the accordion-type water-vapor membrane 1 is extended so as to close the opening of the window, whereas the window 2 is closed, the dehumidifier 1 is folded at an end of the window frame 3. When the water-vapor membrane 1 closes the opening of the window, water vapor permeates the membrane toward a low partial-pressure side, from outside or inside, due to a difference in water- vapor partial pressures. As a result, dehumidification is carried out when indoor temperature is high, without consuming energy.

Abstract: PURPOSE:To provide a cylindrical body with variable outside diameters which can vary exactly and smoothly the outside circumferential surface by forming the outside circumference of said body of plural outside circumferential members, moving the outside circumferential members to form the cylindrical body having an optional outside diameter and winding spirally an elastic sheath thereon. CONSTITUTION:Plural outside circumferential members 1 are slidingly fitted between a pair of side plates 3 and 3 into which a shaft 4 is inserted and are supported by means of parallel crank mechanisms P in such a way that said members move equidistantly in the diametral direction of the cylindrical body. The mechanisms P are formed by connecting a cylinder 5 to be loosely fitted to the shaft 4 and the respective members 1 by means of connecting rods 6 acted as medium nodes and convert the movement of the cylinder 5 in the axial line direction to the movement in the diametral direction of the members 1. The outside diameter of the cylindrical body R is thus varied to a desired value. A thin sheet-like sheath 2 having high elasticity such as spring steel is spirally wound several times over the entire outside circumference of the body R. Such cylindrical body with variable outside diameters has an exact outside circumferential surface and is adaptable to a forming roll device, etc.

Abstract: PURPOSE:To form a thin film of single crystal free from the occurrence of crack, by setting amorphous insulating film having an opening on a base of single crystal, irradiating it with an ionized given substance through the opening so that it is crystallized. CONSTITUTION:When Si is used as a base for a semiconductor of single crystal, the amorphous insulating material layer 7 such as SiO2, Al2O3, SiN4, etc. resisting to at least 1,100 deg.C high temperature, having the opening 8, is formed on the surface of the Si base 6. It is irradiated with Si particles by crystal growth method of thin film using ionic beam. In the operation, the temperature of the base 6 is kept at about 600-1,100 deg.C.
